So I totally have an obsession with eyelashes/mascara...if you haven't noticed yet ;) But, a HUGE factor in having good eyelashes is curling them first. By curling them it gives them a flirty, catching look that mascara alone doesn't do. While mascara gives lashes thickness and length, an eyelash curler does exactly what it sounds like it does: curls your lashes.
Use an eyelash curler prior to putting on mascara- or else it will seriously clump and can cause your lashes to break! I know they may look like some sort of torture devise, but they are very easy to use. Just open, place over your lashes and pull together. I usually do it twice- once at the base of my lashes and once just on the tip of them.
The heated ones work two ways- either just like above, or you comb it through your lashes instead.
You can find eyelash curlers everywhere, but here are some favs:
